Image Converter
Convert images between JPG, PNG, WebP, GIF and BMP.
About this tool
Convert images between formats without uploading. Output quality and size are shown instantly, and WebP usually comes out smallest.
How it works
The source is decoded to a canvas, then re-encoded to the target format using canvas.toBlob with the configured quality. The tool shows the exact output size before you download.
How to use Image Converter
- 1Upload an image in any supported format.
- 2Choose the output format.
- 3Adjust output quality if relevant.
- 4Download the converted file.
Examples
A large PNG converted to WebP is often 60–80% smaller.
A photo with a transparency layer converts cleanly to PNG or WebP.
GIFs can be converted to WebP for dramatically smaller files.
Pro tips
- WebP is the best default for web — small and widely supported.
- Keep PNG for images that need transparency or pixel-perfect detail.
- JPG is best for photographic content without transparency.
